Why Image Specifications Matter
- Rejected submissions - KDP will reject books with images that don't meet their standards
- Blurry illustrations - Low-resolution images appear pixelated in print
- Wasted time and money - Creating images at the wrong size means starting over
- Poor customer experience - Low-quality images lead to negative reviews
Print vs eBook Requirements

- 300 DPI minimum - This is professional print quality
- CMYK or RGB color space - CMYK is preferred for accurate color reproduction
- TIFF or PNG format - Lossless formats maintain quality
- 0.125" bleed - Extend images beyond the trim line
eBooks & Kindle
- 72 DPI - Perfect for screen display
- RGB color space - Matches digital displays
- PNG or JPEG format - Balance quality and file size
